STAGING.

SPECIFICATION forming part of Letters Patent No. 373810. dated February'28, 1888.

` Application filed May S25, 1887. Serial No. 239,312. (No model.)

To @ZZ whom t may concern:

De it known that I, EDWARD E. STROUT, of Lynn, in the county of Essex,State of Massachusetts, have invented a certain new and usefulimprovement in Staging, of which the following is a descriptionsuiiiciently full, clear, and exact to enable any person skilled in theart or science to which said invention appertains to make and use thesame, reference being had to the accompanying drawings, forming part ofthis specification, in which- Figure 1 is a side elevation representingmy improved staging in position for use in erecting a building; Fig. 2,an end view of the same; Fig. 3, an isoinetrical perspective view of oneof the bench-supports detached; Fig. 4, a like view of one of thecross-timbers detached, and Fig. 5 a vertical transverse section of thebench and platform covering ofthe staging. r

, Like letters of reference indicate correspending parts in thedifferent figures of the drawings.

My invention relates more especially to the class of staging employed bymasons in the erection of brick buildings; and it consists in a novelconstruction and arrangement of parts, as hereinafter more fully setforth and claimed, the object being to produce a simpler and moreeffective device ot1 4this character than is now in ordinary use.

The nature and operation of the improvement will be readily understoodby all conversant with such matters from the following explanation.

in the drawings, A represents the body or framework of the staging; B,the windlass; Q, the platform, and C the Wall of the building. The bodyconsists, essentially, of a series of verticallyarranged posts orstandards, .r e, and cross-timbers D. The posts e are erected atintervals in a line or row which stands a few feet from the wall C ofthe building and in parallelism therewith, the companion posts a: beingdisposed in like manner at corresponding intervals, but at a greaterdistance from the wall, as'shown in Figs. l and 2.

The cross-timbers D are provided with mortises l@,in which the posts x zare respectively inserted, said timbers being iitted to slide verticallyon said posts. The posts are preferably arranged about our feet apartand the inner posts, e, two feet from the wall O, each pair ofposts x cbeing provided with one of the crosstimbers D, which are of such lengththat when in position on the posts their inner ends, y, will be nearlyin contact with the outer face of the wall G, straps m being securedtothe sides of said timbers opposite said 6o mortises to re-enforce themand prevent them from breaking at that point when in use. The timbers Dare supported on pins t', inserted in holes b, formed at regularintervals in the edges of the posts a e. t

rlwo staging-planks, d f, are disposed longitudinally on thecrosstiinbers between the A posts x and e, the outer plank, d, beingprovided with notches 40, into which the posts no enter to hold saidplank in position while the 7o platform is being raised or lowered, theplanks f being secured to the cross-timbers D by bolts g, and the planksd by eyebolts 7L.

A bench, J, consisting of a series of transverselyarranged legs orsupports, E, covered 7 5 with longitudinally-arranged plank r, securedthereto by bolts t, is disposed on the platform of the staging, the rearof said bench .resting against the outer faces of the posts e. Fach ofsaid supports or legs consists of a base-timber, 8o 1S, standards 7a,and a cross-beam, l, resting on said standards, said bench-support beingdisposed longitudinally on the cross-timbers D between the posts x z,and the base 1S cutaway on one side at its inner end, at p, to receive85 the standard e.

Planks w are arranged longitudinally on the projecting ends of thecross-timbers D between the posts z and wall C, the inner planks beingsecured to said crosstimbers by bolts 10.

rllhe windlass mechanism B consists of a drum, 12, provided with a gear,45, at each end, and a crankshaft, 13, provided with pinions 4.6, whichiutermesh with said gears, said drum and shaft being arrangedtransversely of 9 5 the platform and journaled in grip-plates K, whichare fitted to slide vertically on the posts 5 w z of the staging, saidplates being secured on the posts by pins 14, passing through the platesinto holes 15 and b in the posts.

IOO

rIwo windlasscs are represented in the drawings-one at each end of thestaging-each windlass being shown as provided with two ropes, 16, whichare respectively secured at one end to the drum 12 and at the other tothe cyebolts h, passing through the cross-timbers D. One of thewindlasses may, however, be dispensed with, as two are not required.

In the use of my improvement, as soon as the workmen have built the wallC as high as it can be reached when standing on the ground, thepostsxzare erected and the crosstimbersD, planks dfw, and bench .Iarranged as shown and described. Theworkmen then attach the windlass Bto the posts a: z', by means of the plates K and pins 14, ataheightthatcan be conveniently reached, and secure .the ropes 16 in the eyebolts h,after which the platform Q may be raised by turning the crank 13, andsecured in position by means of the pins a', in a manner which will bereadily obvious without a more explicit description. After the platformof the staging has been raised a short distance, ties 25 and girders 26are nailed to the posts x, to brace the staging longitudinally, in theusual manner, and when it has passed or par tially passed the windows ofthe building in process of construction braces 27 are secured to theties 25 and window-sills or floor within the building to fasten thestaging to the building. The holes 15 and b are respectively locatedabout two feet apart, as it is usually desirable to raise the platformand windlass as often as the wall rises that distance. When but onewindlass is used, it is moved from one set of posts to another as thestaging is raised and secured in position.

The purpose of the bench J is to enable the hod-carriers to deposit thebricks and mortar used in constructing the wall C within easy reachingdistance of the masons.

By dividing the floor of the staging into two parts, as described, thebricklayers or masons are enabled to occupy the projecting portionbetween thc postszand wallGwhile constructing the wall,without beinginterfered with by the bod-carriers or other laborers who use thatportion located between the posts x and z in conveying material to theworkmen.

I do not confine myself to using the staging in the construction ofbrick-work only, as it is equally well adapted for use in the erectionof wooden buildings.

Having thus explained my invention, what I claim is- 1. The combinationof the inner posts, z, and outer posts, x, provided with pinholes b and15, the cross-timbers D, provided with mor tises through which saidposts are passed, the pins for supporting said timbers on the posts, thewindlass B, the adjustable perforated gripplates adapted to slide onsaid posts and in which said windlass has its bearings, the pins forsupporting said grip-plates in holes of the posts, and the ropesattached to said windlass and connected to said cross timbers,substantially as described.

2. The combination of the inner posts, z, and outer posts, fr, providedwith two series of pinholes, the cross-timbers D, provided with mortisesthrough which said posts are passed, the pins for supporting saidtimbers on the posts, the iioor-planks dfw, secured to the timbers D,the windlass B, the perforated adjustable grip-plates in which saidwindlass has its bearings, the pins for supporting said grip-plates, andthe cords passing over said windlass and secured to said timbers,substantially as described.

3. The combination of a series of vertical outer posts, a series ofvertical inner posts, a platform adapted to slide vertically on saidposts aud projecting beyond the inner posts, a windlass mechanismmounted on said posts and vertically adjustable thereon, and ropesconnecting said windlass mechanism and platform, substantially asdescribed.

4. In a staging of the character described, the drum 12 and crank-shaft13, mounted in the sliding plates K, in combination with the posts x z,means for adj ustably securing said plates on said posts independentlyof the platform, the platform Q, and ropes 16, substantially as setforth.

5. In a staging of the character described, the bench supports or legsE, each consisting of the base or sill 18, standards 7c 7c, and cap Z,said base being cut out at one side, as shown at p, in combination withthe posts :cz and platform Q, substantially as described.
